Resource Estimates
The Onedin and Sandiego copper-zinc-gold-silver deposits are at an advanced stage of exploration with mineral resources defined. In addition, drilling targets have been identified at various other advanced prospects, with numerous other promising zones of surface mineralisation and geophysical anomalism worthy of further exploration and assessment. Click here for a full copy of the latest CSA Global Resource Estimate Report dated 4 April 2022 [insert the link]. Indicated and Inferred Mineral Resources have been estimated by CSA Global for the Sandiego and Onedin deposits in conformance with the JORC Code (2012) as set out below.
